Major redo with respect to chats/contacts -- read desc

Waiting for chats & contacts is hella unreliable, so I've put them as events
1. receive chats via the `chats-received` event. If new chats are found, the flag for that is sent as well
2. receive contacts via the `contacts-received` event
3. When WA sends older messages, the `chats-update` or `chat-update` event is triggered
4. Baileys keeps track of all the changed conversations between connects

Connects almost always take less than 10 seconds!
